1992 70HP Johnson Oil Mixing
 

I finally gave up on this engine smoking. I could not get the oil injection
system to function correctly.
So I have pinched off the oil supply line and am now mixing the oil with the
gas. At present I am using a 50 : 1 ratio but there is still a little smoke.
The engine is on a 24 foot patio boat and is rarely running above 2000rpm.Do
you think that it is safe to go to a 100 : 1 mix?

Thanks, Don and Liz

The following link has an explanation and a cutaway of the oil injection
system along with the true story dispelling the "urban legends" about it.

The oil injection system operates the way it should if there are no air
leaks in the fuel system or any restrictions. All the tests and procedures
are in the late model service manuals.

Older technology 2 strokes do smoke a little. Stay with the 50 to 1 mix.
Use a better oil, such as the Evinrude Johnson XD 50. Make sure the engine
also has the right propeller on it so the engine comes as close to mid
operating range as possible.

It's a half-assed system (VRO) an not worth the risk to run.

Best to use Amsoil and run at 100-1
